Moral Nihilism

Moral nihilism (also known as ethical nihilism or amoralism) is the meta-ethical view that nothing is intrinsically moral or immoral. For example, a moral nihilist would say that killing someone, for whatever reason, is neither inherently right nor inherently wrong. Moral nihilists consider morality to be constructed, a complex set of rules and recommendations that may give a psychological, social, or economical advantage to its adherents, but is otherwise without universal or even relative truth in any sense.

Moral nihilism is distinct from moral relativism, which does allow for moral statements to be true or false in a non-objective sense, but does not assign any static truth-values to moral statements, and of course moral universalism, which holds moral statements to be objectively true or false. Insofar as only true statements can be known, moral nihilism implies moral skepticism.
